Good question for the original poster.
I was just answering to the question of what an "mpeg chip" does.

As far as analog tuners with built-in mpeg encoder chips,
I know of only one: Plextor ConvertX PX-TV402U.

And the drivers for that device are horribly out of date
and didn't work in Mythtv with kernels higher than the 2.6.2x series
(last time I tried it).

Excellent tuner, though, with h264/mpeg encoding etc.. all in hardware.
